. This'invention relates toore sin tering machines and particularly to an apparatus consisting of a train of separate pallets or grates adapted to form a continuous moving grate for continuously sintering the ore fed upon it and discharging it upon the completion of the sintering operation.

An object ofthis invention is a simple and improved means for feeding the ore to the grate in which wearis reduced to a n1ini mum and even distribution of the ore on the grate is accomplished. According to this invention a swinging spout is provided for conveying the ore from the feed hopper to the grate. This spout is ,mounted to swing laterally of the grate and is provided with means to discharge'the ore in the direction of movement of the grate. llhe spout is provided with an aperture in 0 one side Wall and with an adjustable bottom.

The latter is so adjusted that the ore piles up thereon until it forms its own angle of repose and then discharges onto the grate bars. By allowing the ore to, form its own angle of repose in the swinging spout it runs on itself, thereby ellmln ating any wear on the spout.

Other objects, novel features and advantages of this invention will be apparent from the following specification and accompanying drawings wherein:

F ig. l is a side elevation of a sintering ma chine equipped according tojchc invention ig. 2 is an enlarged section on the line 22 of Fig. 1 and Fig. 3 is an enlarged section through the lower end of the spout.

The smtering machine conslsts of a frame 10 provided with an endless track 11 upon which a train of pallets or grates 12 is mounted'to' travel. The grates are elevated and propelled by means of the sprocket wheel 13 which is driven by any suitable source of power 14:. At the end ofthe apparatus adj acent the driving wheel 13 there is provided a frame 15' which supports a hopper 16 to which material to be sintered is supplied by the conveyor 17. g

Below the hopper 16 there is provided a swinging. spout 18 mounted to move transspout 18, passes over a pulley 24 and has its other" end attached to a machine driven.

crank 25. The front face of the swinging spout 18 is cut away as at 26 to provide a discharge aperture and the lower end of the spout is closed by an adjustable plate 27.

The ore to be sintered is supplied to the hopper 1G by the conveyor 17 and from the hopper 16 it passes into the swinging spout 18 and piles up on the bottom plate 27 until the angle of repose is reached. After the ore has formed 1ts own angle of repose it then discharges through the aperture 26 onto the grate bars 12 by which it is carried while the sintering operation is performed in the Well known manner. A I

The spout is swung continuously transversely of the train of grates by means of the crank 25, weight 22 and cables 20 and The ore is thus uniformly distributed over to form its own angle of repose in the swinging spout 18' it runsover itself thereby elimi nating any wear on the spout. The bottom plateis adjustable and when. set by trial at theproper adjustment allows the material to be distributed uniformly over the grate bars. I claim: In a sintering machine having a continuously moving train of grate'bars, ore feeding means comprising a spout hinged at its upper end and having a lateral discharge opening at its lower end, an adjustable bgttom plate for said spout, means to oscillate' said spout and means to feed ore continuously to said spout. v

In testimony whereof, I have signed my name to this specification.
